sub-tasks in iPhone Toodledo app

I just started the free trial to test this. I can't figure out how to create a sub-task on the iPhone toodledo app. The iPhone is my primary means to work with Toodledo, so I need all the capability in that app. Is it able to work with sub-tasks like it says, or does it only view those from the website in a "flat" manner?

Our iPhone application definitely supports subtasks. Just make sure that you have at least version 1.3. If you have an older version that doesn't support subtasks, you'll need to download the free update.
